well i heard that not turning off your pc will let your pc 'last' more longer, is that true? what kind of pc is suitable for that and what kind is not?
thanx for any help.

I always leave mine on. Protected of course with a UPS and firewall software.
I leave my system on.
only on a "add-on" or download need,which is actually a restart, do I shut system down..
Do not know reason for or against.But do vary screensavers, to prevent "pattern burn-in".
There are two things to consider when deciding on whether or not to leave your computer on. The first is Windows related... that the Windows Operating Systems need to be shut off to recover 'misplaced' memory. Software programs, if not well written, will reserve memory space for their operations and will not release that reserved memory when the program terminates. The only way to recover this memory space is to restart Windows.
On the other side is physical. Everytime you shut down your computer, you allow it to cool. When you start the computer, it heats up. This heating and cooling causes stress on the computer's components. When a metal heats up it expands and conversely contracts when cooled.
Computers are engineered to take this effect into consideration, and typically are designed to take thousands of these cyclic stresses. BUT...no matter how you look at it, there are only so many cycles of heating and cooling that a computer can sucessfully survive. My point is that you damage your computer everytime you turn it on and off allowing it to cool.
What I recommend is to leave the computer on, and restart the computer once per week without allowing it to cool.
The only component of a madern PC that uses measureable electrical energy is the monitor. Set the monitor to automatically shut off after 30 minutes. This should satisfy all the 'green' people. Don't leave a screen saver on. That is a waste...
Hope this helps.
Re:On in the AM and off at nite for me...nt
Like, its always on dude
I have a server w/ linux and I will tell you, for running a personal server, I keep it on 24/7. The thing is though, it actually stays on and comes to w/o crashing, so don't try that with Windows.
Turn it Off/Leave it ON
With all Windows Pre-XP a system left on would eventually hang and need to be turned off. I've since heard that Win ME is one that only has a 48-72 hour time frame before it needs to be turned off. (on another forum?)
We now have Win XP and all maintenance programs and updates are set to run while we sleep - Only time it's off is when a storm rolls through or cleaning up some game The Child downloaded.
I did a little research and found the following link. It has some interesting information and leads me to say, turn them off. Here is the link:
I hope that this is useful to you and to the other readers.
Usually, I turn my computer on hibernation mode, instead of turning it off. Hibernation mode is just like shutting down the comptuer except that all the data that is on the RAM is placed on a section of your hard disk, then turning power off to your computer. It means that all power is shut off to your computer, however it lets you start your computer up directly to where you were. This is important if you have alot of startup-processes, or if you are just wanting a much faster startup. The only time that i personally turn off my computer is when Windows requires a restart.
It will do no harm to leave your PC on and will lengthen the life of your hard drive. This limits the thrashing the hard drive will have to do on power ups. Most PC's sold now,and for the last 10 years are okay to have this done. And it is also a good idea, if you want to conserve electricity to have your PC go into hibernation or sleep mode after a certain amount of time and also have it connected to a UPS or surge protector.
I can't tell you how many times I've had light bulbs blow-out when I've gone to turn on a light. Sure, I've had bulbs that have been on awhile flicker and burn out, but those are generally cycled on and off a couple times a day, which appears to weaken the filament.
FWIW, my computers -- desktops, servers and laptops, both at home and at work -- are on 24/7 but go into low-power sleep mode (exc. the servers ;)) and I can't tell you the last time I had a machine suffer a serious failure other than hard drives (and even those are rare.
if you have the right cooling in your pc its not a problem leaving it on 247, but you may find that your system slows down after long periods, asdl conectins may also time out and a re boot will be needed to get a conectin agian
Re:turning off PC
I belive that if you are going to come back and use it in the next 2 hours leave it on. If not turn it off. The hard drive is spinning constantaly unless you use power saver to stop that. I have had to much trouble waking up computers that use that feature. Do you leave your car running till you use it again or most any other device.
Re: turning off PC" = Good/Bad
leaving it on wont hurt anything .. I ran a PenII 350 mhz with win98se for 4 yrs without turning it off except to reboot once every other day or to clean it. .. I am now running Pen 4 2.6 ghz with win xp and only turn it off to reboot .. My 2 children and I share the PC so I have all my scheduled tasks ie; defrag, virus scans etc run while I am sleeping that way we dont lose any computer time. the only precaution that needs to be taken is the need to have more then just a good firewall if you are using a braodband connection to keep out hackers and other little nastys from invading your machine
Re: turning off PC" = Good/Bad
Do you have it on 'Hibernate' when you leave it on?
In the beginning (1981) PC's had no constantly moving parts. No hard drives, CPU fans, etc. Therefore the theory was to treat it like a light bulb, the less times you turn it on the longer it would last. Today's PCs have many moving parts like hard drives, CPU fans, etc. These parts wear and dust is sucked into the PC while running. Leaving a PC on connected to broadband is never a good idea. PCs that are left ON are at much higher risks from electrical power failures and lightning. Not too many things can hurt a computer when it's OFF. Also PCs perform self check routines during startup that can lead to early detection of upcoming problems. All in all, unless there is a valid reason, sleep with your PC and your car turned off.

Re:turning off pc, good or bad?
I have seen all our computers in our work place always turned 'on'. They are never switched off! if you have a spike buster or spike guard , you don't have to worry about keeping the system 'on'. But if you have voltage fluctuations often , then it is best to switch 'off' the computer after every use. The latest computers are energy efficient and savers . I switch off my personal computer when i am done!
When you are done, make sure you are not connected to the internet. as long as the computer is 'on' and not connected to the internet, you are ok!
Re: Turn-off or Leave-on Your PC
The PC OS since the 98SE is designed for the system to be on. The system will last longer if the system is left on and not left off. The problem with turning your system off is that you are constantly heating and cooling the components in the system of which eventually will crash and fail. You only have to reboot or warm boot your system when you have it on about once a week to flush out memory. This is why your OS is equiped with hybernation, sleep mode and safe mode, so that you do not have to turn off your system. Turning off the system also allows the number one killer of PC's to set on your system and that is dust. My PC's stay on 24/7 and I have not had a crash yet. My daughter turns hers off...I had to replace several parts on her system.
Re: "turning off PC" = Good/Bad
I have previously left my PC on most of the time for years. Now I believe because I have problems w/errors due to overheating, I am shutting down (which solves my errors). Not sure what caused the overheating, I think it is age, still I am not sure what is right for the longevity of a PROPERLY cooled processor. I have a 1gHz AMD...
I never turn off my pc's, lap top or desk top. I do not think Ihave any more problems with them then ones that are turned off. I always leave the work pcs on also. Of course, if on vacation or business is closed, then all is turned off. You never turn off the server do you? What makes the difference.
Turning off your pc has many benefits :
1.-- increases security- you can't be hacked if your pc is off. another security item is to disable autoconnect in your browser(worms and hackers can't take over if they can't get online.
2-- saves power
3-- ensures privacy
Yes it saves power but the cost of maintenace and replacement will cost you far more in the long run. Now as to security disconnetc your network cable. No out side connection possible End of Story.
Re: Leave it on!
There is much less stress on the hard drive if the computer is left running. My computers are only shut down for modifications or during thunderstorms (I live on top of a mountain in a very rural area).
Re: Turning off a PC Good/Bad
I have heard from different people on this subject many times over the years. I keep my home PC's on 24/7 connected to an UPS to guard against surges and have automatic shutdown software. At work we do the same, our PC's and servers are on 24/7, the only time we shut them down is when there is a scheduled power outage so the UPS's are not rundown. I believe as long as you have adequate ventilation for the processor(s) and other heat generating items, keeping it on will not harm it.
Re:turn on or off?
I am a computer tech who works on others computers almost daily. My own computers that I use at home remain on 24/7. Years ago I had turned them off at night and would have a part go out now and then. When I opted to leave them on I noticed that I did not have a part go out on them so I continued to leave them run. I have a computer (my main one) that has been running for two years and the only time I have shut it down was when I added a new piece of software that required a restart. No part has gone out during that two years.
Unless you are using your desktop computer as a server, turn it off when not in use. Being a broadband user is more reason to turn your computer off. If your computer gets hit with a virus or becomes an open relay, it can't send anything out if it's turned off.
If youre working the next day and use your PC for long hours then leaving it on maybe more cost affective then shutting it down. It takes more power to boot up your PC then to place your system in suspend or stand bye mode. However if your not using your PC for 8 or more hours a day and will not use it for the weekend or longer I recommend shutting it down. Why because you still use a very small amount of electricity when it is in suspend mode.
Leaving on the PC is NOT the end of the world or the
end of your PC.
Prior to PC's there were these things called Mainframes.
They were on ALL the time, most still are, in fact webservers are on all the time so that when you wake up in the middle of the night you can... check this out... Get you Email! ooooooo shock gasp!
Look get a battery backup with a surge protector, if you haven't already you need a typewriter not a computer. And leave the thing on. Its not like the WIN 3.1 days where you need a screen saver, worry about spiking this or that. Set you power settings in your control panel (if you are Win user) to put to sleep the hard disk and the monitor after X amount of time.
Why wait for the system to boot from cold, when you can
just wake it up with a keystroke or mouse move. Sooner or later some smart company will make the PC that behaves like a PDA and load the OS in a chip for instant on. Until then leave the thing on. If you are worried about hackers, get a Hardware Firewall (like you shouldn't have that as well!) and don't worry, its ONLY a machine.
Re: Turning off PC = Good/Bad
There are pros and cons with this matter. In my opinion, it depends on the software applications you are running and your power bill. Example, applications that require the system to be on constantly, such as data collection system servers, Network Servers, Backup systems need to operate constantly in some cases to track and record vital or critical information. You will however, save wear and tear on the hardware components, e.g. CPU fan, power supply unit etc, by shutting down the system regularly. I shutdown my 2 computers at the end of each day. They switch to standby during the day, with the monitors off automatically, during the times throughout the day that I am not using them. (I run an on-line system diagnostic service). I haven't had any harware failures as of yet, after working with my first computer (bought 8 years ago), by shutting it down at the end of the day. It is slow by today's standards, (166MHz) but still running well with Windows 98 on it as the first upgrade 6 years ago. Then a 32MB module added for a 64MB RAM upgrade. plus regular software maintenance and general upkeep. My new system has Windows XP. No harm done to it, either by shutting it down everyday. It's Not good to start up, then shortly shutdown the PC. This stresses the components and shortens their life. The debate goes on...........
I've owned and used several computers and have used daily shutdowns on some work computers, leave it always on on home computers and combinations on most. Windows (I have XP home, ME, 98 SE) doesn't seem to be able to run more than a few days without self destructing. It becomes necessary to reboot or restart ususally daily. If a computer is not used daily, I shut it down until it's needed (three computers). The one I keep running goes into hybernate after 20 minutes and the monitor (17" LCD) shuts down. It's faster coming up than a reboot, and seems cooler.
